Problems solved by technology

The working environment of the Arara Grinding Machine is harsh, and the high-temperature and high-line-speed grinding metal particles generated during high-speed grinding are scattered everywhere, making it very difficult to directly measure the diameter of the grinding wheel
Indirect measurement using a laser sensor is a solution, but the outer circle of the grinding wheel is in a high-temperature and red-hot state during grinding. Ordinary lasers mark the measuring points on the grinding wheel, and sometimes the return signal may not be received or even cannot be received.

Embodiment Construction

[0069] The present invention provides an on-line measurement method for the diameter of a grinding wheel of a high-speed powerful conformal rough grinding machine. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0070] The concrete steps of this method are:

[0071] 1) Hardware configuration and installation: Based on the specifications of the mill and the on-site production environment, there are corresponding requirements for various indicators of the laser sensor, the most important of which are range, accuracy, frequency and stability. This solution uses a domestic laser displacement sensor with a range of 0.2~70m, an accuracy of ±1mm, and a maximum frequency of 10Hz.

[0072] The high-precision displacement measurement laser sensor 1 is installed under the support arm 4 of the waste mill, which not only avoids sparks splashing around during grinding, but also avoids the increase of errors caus...

Abstract

The invention relates to an online measuring method of the diameter of a grinding wheel of high-speed powerful shape-followup snagging machine, belonging to the technical field of engineering measurement. The method comprises the following steps of: establishing a workpiece and grinding wheel diameter associated model through a motion mechanism model of the snagging machine and alternating shock vibration data analysis based on process statistics; acquiring high-precision grinding wheel diameter data with a simple measurement method by using a high-precision displacement measurement laser sensor under a large-vibration and strong-interference background; and correcting errors of the high-precision grinding wheel diameter data. According to the invention, a corresponding real-time data support is provided so as to realize the optimized grinding effect and reduce the grinding wheel loss.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement, and mainly relates to an online measurement method for the diameter of a grinding wheel of a high-speed powerful conformal rough grinding machine tool used in rough processing equipment in the metallurgical industry. Background technique [0002] The heavy-duty high-speed powerful conformal grinding machine is a kind of rough processing equipment in the metallurgical industry. The optimization of its grinding control is based on the real-time acquisition of various operating parameters, especially the measurement of the diameter of the grinding wheel. The working environment of the Arara mill is harsh, and the high-temperature and high-speed grinding metal particles generated during high-speed grinding shoot everywhere, making it very difficult to directly measure the diameter of the grinding wheel. Indirect measurement using a laser sensor is a solution, but the outer circle of t...
